Full Stack Developer
Knak Digital
Our client has been building digital products for government agencies and businesses for over 20 years. The work is technical, the clients are high-visibility, and the team is small by design. Everyone here owns their work.
This role is for a senior full-stack developer who is comfortable making technical decisions, working directly with clients and stakeholders, and mentoring the engineers around them. AI integration is a real part of this work, not a checkbox.
What you'll do
- Lead full-stack development across React, Next.js, Node.js, and TypeScript
- Design and integrate RESTful APIs, GraphQL endpoints, and AI-assisted features including LLM-powered workflows and RAG
- Work directly with clients to translate requirements into technical solutions
- Make architectural decisions and hold accountability for them
- Mentor junior engineers on modern JavaScript and AI-augmented development practices
- Evaluate and adopt AI-assisted tools (Copilot, Claude, automated testing) where they actually improve the work
- Contribute to CI/CD pipelines, cloud architecture, and DevOps practices
What you bring
Required:
- 7+ years of software engineering experience, bachelor's degree or equivalent
- 5+ years of professional JavaScript/TypeScript development, front-end and back-end
- Strong React or Next.js experience building responsive, production-grade interfaces
- Node.js proficiency with frameworks like Express or Fastify
- Experience designing and consuming REST APIs and/or GraphQL
- Solid understanding of relational or NoSQL databases (PostgreSQL, MongoDB, or similar)
- Git and modern CI/CD workflows
Preferred:
- Prior government contracting experience
- Cloud platform experience (AWS, Azure, or GCP)
- Hands-on experience integrating LLM APIs (OpenAI, Anthropic, Azure AI) into production apps
- Familiarity with RAG, prompt engineering, or agentic workflows
- Docker, Terraform, GitHub Actions
- Section 508 / WCAG accessibility standards
- Agile methodologies
Compensation Range is wide due to leveling (1 and 2). Range depends on experience level.
Level 1: 115-135k.
Level 2: 135-170k.
Clearance requirement
Must be a U.S. citizen or legal resident. This role requires the ability to obtain a Public Trust clearance.
